Medicare D and Costly Biologics Save

25% of Medicare beneficiaries with rheumatoid arthritis use high-cost biologics.  Yazdany and coworkers have analyzed a national cohort of beneficiaries and compared Medicare part D plans. Nearly all Part D plans cover at least 1 biologic DMARD, but the vast majority require cost sharing that is sufficiently high to risk significant financial burden to patients.  Most patients incurred out-of-pocket costs of $2,712–$2,774 before reaching the donut hole.
